I set up an automation in the new app. Simple, on fall of temperature turn on a smart plug. On rise turn it off.
The automation is not showing up on theclassic app.
Is this normal?
Yes. Custom Automations are only available in the STSC app and not the Classic app.
btw: New App “Scenes” can be created in the New App and can be activated (but not edited) in the Classic App.
